一、取原状土样的目的意义在基础工程勘察中,对软基均需采取样品(这类样品通称土样);对土样进行试验,了解该软基层的天然结构、组织成分、密实度、自然湿度、孔隙度、节理程度、抗剪强度、压缩系数、容量、渗透系数等,从而确定软基层的承载力和稳定性。也就是说,为了确定其物理力学性质,获得工程设计与施工所需要的可靠数据,就需要解决原状土样采取的技术问题。土样的采取质量,直接影响着所求得的软基层参数的真实性,关系到构筑物设计的合理
First, the meaning of the purpose of taking the original soil sample In the basic engineering survey, the soft ground are required to take samples (such samples commonly known as soil samples); soil samples were tested to understand the natural structure of the soft grass, tissue composition, density , Natural humidity, porosity, joint degree, shear strength, compression coefficient, capacity, permeability coefficient, etc., to determine the bearing capacity and stability of the soft grass. In other words, in order to determine its physical and mechanical properties and obtain the reliable data needed for engineering design and construction, it is necessary to solve the technical problems of the original soil samples. The quality of soil samples directly affects the authenticity of the soft ground parameters obtained, and relates to the rational design of the structures.
